Plattsburgh lies just to the northeast of Adirondack Park, immediately outside of the park boundaries. It is the second largest community in the North Country region (after Watertown), and serves as the main commercial hub for the sparsely populated northern Adirondack Mountains. Plattsburgh was the site of the amphibious Battle of Plattsburgh in the War of 1812, a key American victory that marked the end of hostilities in the Northern United States. It has been an important military outpost for much of its history, from hosting one of the largest Citizens' Military Training Camps prior to World War I, and Plattsburgh Air Force Base, the east coast center of operations for the Strategic Air Command during much of the Cold War period. The conversion of the base to a civilian airport in the 1990s resulted from the Base Realignment and Closure process during the wind down of the Cold War, and today it serves as a hub for economic development for the region. The city was named one of the Financial Times Top 10 Micro City of the Future several times.
